Can't say the battery life of my 3GS has diminished at all.
Do a search for the advice about disabling and reenabling push on your mail accounts. If memory serves, that was draining batteries for a few people using the OS4 GM.
A few weeks back I updated from os4 to the second version and ever since my battery life has diminished beyond belief.
I have gone from the battery lasting all day with just a charge overnight to needing to charge it around lunchtime and again in the evening and then overnight!!
Anyone else suffering, done some trawling and Apple are saying there is no problem.....I beg to differ :evil:

iPhone battery life does seem to be handset specific, some being fine whilst others being rubbish :(
Shame the battery is an Apple Replacement item only... sadly typical of Apple really.
Wife's 3GS is on 4.0 and is fine, my 4 is on 4.0.1 and some days are better than others!
I don't notice that on the 3GS of my wife.
Out of curiousity, did you jailbreak and use winterboard?
No factory spec never tampered with.
Looks like I am not alone :cry:

I had a similar issue with my 3gs.... in my case restoring it and setting it up from scratch resolved the problem.Originally Posted by spogehead
Thanks Oliver, was that with os4?Originally Posted by bricktop
No, wasn't OS 4... I guess it was 3.1Originally Posted by spogehead
To me it seemed that the backup I had was somehow defective and that made the battery lose around 10% per hour. After setting everything up from scratch I didn't have any issues anymore.
Of course it might not help in your case, but it's worth a try. If it fails you can always restore your last backup.
Annoys me that a few things have been ruled out by Apple.Originally Posted by Jonmurgie
For instance - why can't i Btooth stuff from phone to ipad? Same companies products ffs!

When you look long into an abyss, the abyss looks long into you.........
I did a bit of housekeeping on my 3G and the battery life doesn't seem too badly degraded. The speed is the main downside of the new OS. With the amount of money I have ploughed into apps, it's forcing my hand toward the iPhone 4, having handled one at the weekend, the screen is stunning.
Call me cynical but does make you wonder if the update is really an update......to have my battery life draining like it is (along with many others according to the apple forum) and numerous stories of os4 slowing up 3g models, iphone 4 will no doubt attract many who were holding out for upgrade time.Originally Posted by IANAN
No real difference on my 3g - I suspect it is app and setup specific?

Well, same here actually. 4.0 was kinda ok, but 4.01 is a nightmare.
WiFi, GPS, push/notifications deactivated, no winterboard. But all I get is about 8 hours (just a few phone calls, emails, texts).
Already did a full restore, but it didn't help at all. I'm really pissed.
I'm not as think as you drunk I am.
I didn't notice any change in battery life on my iPhone 4. Still get around two days (WiFi, pushmail on)...Originally Posted by mr1973
Yes, but the 4 got a better battery ;-)Originally Posted by bricktop

Interesting thread, unfortunate to hear some issues :(
Mine is absolutely fine, battery performance defo an improvement over the 3GS for me - now a couple days between charges instead of having to give it a quick blast each evening before it went AWOL.
I know... but what I meant to say is that I didn't notice any decrease in battery life after updating to 4.0.1Originally Posted by mr1973
Neither did I. I suspect those having problems are victim to a single troublesome app that hasn't been updated for iOS4.Originally Posted by bricktop
Well, not really. Did a complete "reset", with just the OS on the phone...Originally Posted by Seamaster73
I'm not as think as you drunk I am.
I've noticed that the battery does deplete at greater rate of knots before the upgrade to iOS4 on my 3GS but I can live with that.
My main issue is the random rebooting during calls. This is vitually making the phone unusable. I'm not the only one either - 60 pages on the Apple site - http://discussions.apple.com/thread.jsp ... 0&tstart=0
I'm seriously contemplating downgrading the os as there is no sign of Apple acknowledging that there is a fault (although some peeps have had there phones swapped out but many who did ended no better off). Not chuffed having an expensive PDA instead of a phone! (I'm not a MAC beater; having a MacBook Pro, iPad, iPod, and iPhone!)
With regards to upgrading to iPhone 4 my thoughts are to miss this version out and wait for iPhone 5 when the antenna issues and iOS issues have hopefully been resolved. Having an iPad means I now use the iPhone less and less. Really only use it for making calls (so mega frustration with booting issue) and checking emails, so I don't feel the need to splash out for what in essense is only a better screen.

That's that theory knocked on the head then!
My 3GS seems fine on OS 4.01.
That said, I make sure I close apps properly when I finish with them - double tap the home button so that the "dock" of "background" apps comes up, hold on the icon and delete it from the temporary memory.
Allegedly these background apps are only using the Unix "pause" command, but they certainly eat up memory and I think they use battery power accordingly.
The Apple background mode seems a bit rubbish and I would rather be able to turn it off.
After a bit, well loads in fact..... further research I deactivated spotlight search and rebooted, Bingo!!
Back to normal today in fact possibly marginally better than at anytime in fact..................... off charge at 6.30 this morning few calls, words with friends(online game with push),some text, emails etc and I currently sit at 55%.......with the same usage yesterday I had already charged once around noon, and was sat at 27%
It appears that spotlight keeps indexing in the background which is chipping away at the battery and keeping the phone in use whilst idle.
This has worked for me:
settings/general/spotlight search and then untick the lot......I have never used it so not an issue for me and a bit piss poor that I need to switch off but...........I like my iphone again :P
Thanks for the tip Ryan, have to try that out now. Will report, Sir. :)
I'm not as think as you drunk I am.
That's been tipped for a while for the 3, but I'm sure I read the effect is supposed to be marginal on the 3GS?
Well done mate! Never even knew about this, duly switched off :DOriginally Posted by spogehead
BTW I too wish we could switch off the "multi-tasking", it's a pile of pants!
Great tip, will also turn off spotlight on my iP4 :)
Give it time mate, it will get better as more apps use the feature... but I do agree that in the main they are simply a shortcut to the last 4 things you had open (if you don't bother scrolling to the right). Never bother with it myself, and apparently it doesn't have any affect on the phones performance or battery life if you leave things 'open' in the bar... not sure how true that is but there we go.Originally Posted by GraniteQuarry
That's the concern isn't it!Originally Posted by Jonmurgie
And of course it's never just four LOL... scroll right... scroll right... :lol:
Useful though when, for example, you are using a SatNav and you get a phone call - before the app would exit when you answered the call.
Turned off the automatic e-mail updating and battery life improved dramatically.
The one issue I've been having since upgrading to OS4 is I now keep getting the error message "Charging is not supported with this accessory". Apple Support have no idea why. So I've to send it in for them to look at - which means no phone in the meantime, and still paying my £35 pm. No at all impressed with my first Apple. :evil: [Sometimes think I should have stuck with my £10pm PAYG cheap Nokia ...]
I still have a 2G on PAYG, my son updated it (which took ages!), it wouldn't accept charge after that and very nearly went in the bin!!
he removed the upgrade and - Presto!!, it was OK again 8)
John :P
I think I have a full set!
Since upgrading to new OS on my 3GS
1. Phone regularly resets itself mid call or sometimes just for the fun of it
2. Regularly get 'this device is not compatible for charging etc.etc.'
3. Battery life is very poor
Tried all sorts of things. Back up, wiped phone and reinstalled - seems slightly more stable
turn apps off, turned off spotlight search etc.
Got a new SIM which does seem to have helped with the resetting issue - it only did it once yesterday instead of about 5 times a day usually.
I've found my carrier (O2 and Apple to be of little help) - each seems to deny the existence of any problems even with the damning evidence elsewhere.
I thought I was going to be a loyal iPhone user (this is my second) but my current experience is starting to turn a lifelong advocate of Apple into a doubter!
I noticed a real improvement with OS 4.0, quite remarkable infact.
However since I've updated to OS 4.0.1 I have noticed a sharp drop in life - I need to charge it up around mid afternoon.
I also seem to be no longer able to send media messages. And how do I fix this? Go to an Apple store... joy of joys
